STAMPING APPARATUS, n PARTICULAR FOR MARKING ARTICLES To BE LAUNDEREDKTo all whom it may concern:

Be it known that we, ARTHUR HAMMER, a subject of the Emperor of Germany,and resident of Berlin, Germany, and FRITZ Esnnsnonrnu, a subject of theEmperor of Germany, and resident of Berlin-Oharlottenburg, Germany, haveinvented certain new and useful Improvements in Stamping Apparatus, inParticularfor Marking Articles to be Laundered, of which the followingis a specification. I The present invention relates to a stampingapparatus which is chiefly intended for marking articles to belaundered, and in which the inking device is, at the commencement of thestamping operation brought into contact with the stamp and thereuponagain moved away from the latter, In the heretofore known stampingapparatus of this k nd the inking device is during such moving away orat least during the first part of such movement'still in. contact withthe stamp, so that it wipes along the latter and the inking is notperformed in the mostfavorable manner.

According to the present invention the inking device is broughtintocontact with the stamp and again removed therefrom before its movingaside is started. For eb- 30 taining this object the inking device maybe fitted to 'a carrier which'receives an upand down-movement before theasidemovement.- In the accompanying drawing a construc- 35 tional formof the new stamping apparatus is exemplified; in this drawing- Figure 1is a side elevation, partly in section along the line II in Fig. 3. 1

Fig. 2 is'a section along the line II'TII in 4e Fig. 3.

' 'The stamping device 1, which is composed, in the usual manner, of aplurality of disks having printing types 66- (omitted in Fig. 3) on"their circumference and dis- .55 posed to be set atwill, is journaledin a Specification of Letters Patent.

carriage 4 which is vertically guided on the machine body 3. Theindividual disks of the stamping device 1' are arranged close besideeach other on a shaft 35, which is fitted in the walls of a casing 2connected to the carriage 4; by means of telescoped tubes 37 the saiddisks are coupled to chain .wheels 36 in the said casing 2. Over thesechaln wheels 36 travel endless perforatedsteel bands 42 which act asdriving chains.

These steel bands 42 travel also over guide rollers 39 fitted loose on ashaft 38 in the upper end of the casing'2 and besides over tensionrollers 41 fitted loose on a shaft 40, which is jo-urnaled by means ofan eccentric pin 64 in the casing 2 so as to allow of regulating thetension. In the front wall of the casing 2 are-provided slots 43 extending from the top downward. Through these slots project handles44attached to the individual bands 42. Along'the sides of said slotscharacters, such as "numerals, letters or the like, corresponding tothose on the character, the said character on the respectivestamping'disk will be in stamping'position. The handles 44-are-provided'with conical shoulders 44 which correspond to recesses 63in the sides of the slots 43(Figs. 2 and 5). The resilient steel bands42 will draw the handles with the conical shoulders 44 into the recesses63 and thereby lock them, so that theymust firstbe pulled out when thetype wheels are to be reset. The

' circumference of the disks are indicated in series in such a mannerthat when thehan- 'dle 44 of a given band is set to anysuch.

stamping is performed by movingthe carriage downward, whereby the settypes of the type wheels are printed onto the article placed upon theelastically supported table 45. For moving'the carriage 4 downward, thefollowing arrangement is employed.

In the machine body 3 is journaled a shaft 9, on which a toothed segment10 is fitted. On a lever '11 fitted to the same shaft acts arod12connecting with a foot lever. A returning spring 67 acts upon said rod12. Fitted to the carriage 4 is a rack '8 (Fig. 2) with which thetoothedsegment 10 turning clockwise as seen in Fig. 2, meshes when the footlever is depressed, so thatthe carriage 4 with the casing 2 is moveddownward. When the foot lever is released the riage 4 returns underaction of the returning spring 67 into lifted position. For facilitatingthis movement the weight of the casing 2 is balanced by means of acounterweight 47 fitted to a double-armed lever 46. This lever 46 actsby means of a link 48 on the casing 2. The carriage 4 is arrested bothin raised and in lowered position by means of an elastic bolt 49, whichat thetwo terminal positions of the carriage 4 engages in correspondingspherical bores 50 and 51 respectively in the latter.

A bar 23 (Fig. 1) carrying the inking device 21 with the inking pad 27is shiftably fitted in a U-shaped guide 22 which is under action of apressure spring 5.5. This guide, 22 is pivotally supported by aid of apin 30 in a bearing 53. The guide 22 has at its upper end a longitudinalslot 54 (Fig. 3) through which the end of a lever 19 pivoted at 18engages in a slot 20 of the bar 23 which is under action of a returningspring 34. The said lever 19 is under the control of a cam 32 fitted toshaft 9, by means of a roller 33 fitted to the side of said lever. Thiscam has aconcentrical portion 32 which in the position of rest (Fig. 1)is in contact with the roller 33.. In this position a lug 32 of the cam32 abuts against a lug 31 of the guide 22.

When by pressing down the foot lever the shaft 9 is turned clockwise,the guide 22 will, by the action of lug 32 of cam 32 on lug 31, be movedcontrary'to the hands of a clock, so that the inking pad 27 is pressedagainst the types of the stamping device 1 opposite to it. In the nextmoment the lug 31 is cleared, so that the guide 22 will return underaction of spring 55 into the initial position. Then the roller 33 willleave the concentricportion 32 of the cam and slip on to its side 32(Fig. 6), so that the spring 34 can pull the inking device 21 away fromthe range of the stamping device 1. Only after this operation has beencompleted, the toothed segment 10 comes into engagement with the rack 8and moves the stamping device 1 downward.

: l/V hen the foot lever is released, the stamping device is firstraised, whereupon by the action of the side 32 of the cam 32 the lever19 and with it the inking device is moved toward the right as seen inFig. 1. Toward the end of'the return movement the cam 32 passes over thelug 31 and bears against it.

The inking device may, itself, serve as receptacle for the ink; in theconstructional form shown, however, it consists of a plain inking padwhich comes, at each stroke into contact with the ink receptacle forreceiving a fresh supply of ink. The ink receptacle which is open at topand bottom and is fitted to the side of easing 2 of the stamping devicelcontains a porous substance saturated with the ink, onto which fresh inkmay be poured after the lid 58 has been opened. At the position of rest(Fig. 1) the lower opening of the receptacle 57 is closed by means of aplate 59 fitted to lever 19,-in order to prevent the ink from drippingout or being evaporated. I Vhen the apparatus is employed, together withtheaside movement of the inking device 21 the plate 59 is lifted fromthe receptacle 57, which is in such position that when the inking deviceis fully moved aside, the inking pad is vertically beneath it. In thesubsequent downward movement of the carriage the ink receptacle willwith its open lower side set down on the inking pad 27 (Fig. 6) so. thatthe latter receives a fresh inking, which it will, at the followingoperation transfer to the printin types.

In combination with the stamping device 1 is provided a device forarresting the individual type wheels in their set up position. Thisdevice consists of a corresponding number of bolts 60, under action ofsprings 62, and disposed in a carrier .61 at the side of the casing 2.These bolts may engage with their beveled ends into correspondingnotches in the type wheels.

I claim 1.
